Ideopsis vulgaris macrina

Fruhstorfer 1904 - The Dark Blue Glassy Tiger

Koh Samui and Koh Pha Ngan.

Very similar to Ideopsis similis, the main difference being the shape of some of the basal spots in spaces 2 & 3 on the forewing, which, in I. similis are elliptical and I. vulgaris, wedge shaped. Also, the cell-end spot is only slighly outwardly indented in I. similis, but deeply indented in I. vulgaris.

It is also the rarer of the two Ideopsis species found on Samui.
